3 waxing methods
Use a giant rubber band around 1 brake arm, over the back of the binding, then over the other brake arm to hold the brakes back (we use the ones that come on raw broccoli or cauliflower). Flip the ski upside down (obviously) onto the back of 2 really heavy chairs or something else that will support both ends (unless you happen to have a work bench with a vise).
The most wax usage, but the best coverage and the easiest: heat the iron just so the wax melts, then holding the wax bar to the iron above the ski, run a string of drips down one side of the base then up the other. This should give you enough wax to cover the ski easily. Working from tip-to-tail and keeping the iron moving constantly, iron the wax into the base until the ski is covered completely and evenly. Set this ski aside and do the other one. When you're done waxing the 2nd one, put the first one back up on your "bench". Again, working from tip-to-tail, use the scraper to remove
all the wax you just put on. Seems stupid, doesn't it

? You only want to leave on the wax that actually soaked into the base of the ski. Scrape the other one. You're done!
Some wax waste and 2nd easiest: Rub the cold wax bar vigorously over the entire ski until the ski is completely covered with waxy guck - this is called 'crayoning' the wax on. Then iron and scrape as above.
No wax waste but the most difficult: As above, crayon the wax into the ski. Then with a cork ($3-10 USD) or a very thick, rough towel, rub vigorously with lots of pressure from tip-to-tail until the ski is smooth and shiny. This is seriously hard work!

If your skis are really dirty or 'gooky' looking (like from midwest spring snow), you may need to clean your skis before beginning. You can use a citrus-based 'base cleaner', or just apply a thick coat of wax and scrape and rub thoroughly while the wax is still hot from the iron.
That's the basics! It's easy :D !! Have fun.
